63' Johnson 10hp Throttle issues

[R-J]

Hello, I have a 1963 Johnson Qd-23 10hp Outboard where the throttle is slipping.
I have taken off the tiller And that doesn't seem to be the problem.
I pretty sure the problem is In-between the Throttle gear or bushing and Throttle lever.
If anyone has any idea of where to find these parts or how to fix the issue please let me know.

Thanks,

gears may have slipped see LEROY'S article on later models. not saying it is your problem but check gear meshing


The One Weak Thing on This Motor : The first series (that I designate as type 1) up to and including early1986, uses twist grip gear teeth to activate the throttle on this series. As described above these gear teeth mesh on both the twist shaft and the mating linkage shaft gear function so that the handle can be raised or lowered and yet be twisted. BUT this feature was not really intended to be used this way as mentioned earlier under "Remote Controls". DO NOT RAISE the handle very high AND twist the throttle unless you are prepared to disengage the gears, which changes the twist grip timing relationship. This is explained in a subsequent section. Pictures show this relationship in the Trouble Shooting section. The main problem occurs if these motors are being used as an auxiliary motor on a sailboat, where the tiller handle has to be tilted upward and WILL get out of engagement easily. I have looked at this situation a lot and have not found an easy method of correcting the problem.
